Is Kimi-K2.5 or GLM-5.2 smaller?

Both publish quantizations; compare the table for the exact sizes.

Which uses less memory at long context?

Kimi-K2.5 — its KV cache at 32K context is 1.3x smaller, because of how its attention layers cache.

Model comparison

Kimi-K2.5 vs GLM-5.2

These two publish different quantization sets; the table below has the exact sizes. At long context the gap widens: Kimi-K2.5's KV cache at 32K is 1.3× smaller, which usually matters more than the difference in weights.
